We can launch applications and scripts as services during boot at various Linux run-levels as demonstrated earlier, however at-times we need to launch applications or perform scripted tasks only after the Graphical interface is loaded. For example in my usage scenario with Debian running on a Raspberry Pi, few services were failing to work as expected when launched using inti.d method as they require the host to be properly connected to the internet which only happened (in my usage scenario) after the GUI started loading.

Here is another handy way to auto-launch applications and scripts in a similar manner to "autostart" in Windows, we will be using LXDE "/home/pi/.config/autostart" folder to create shortcuts which will launch our executable after GUI starts loading.
